It is a popular rock garden genus with many horticultural representatives. One of these, A. maxima, an annual Eurasian species growing as a single rosette, was reported in the late 1800s as an introduction near Yonkers, New York. We have no recent records that suggest this was anything more than an ephemeral horticultural escape.</p> |tables= |references= }}<!-- --><div class="treatment-key"> ==Key== <div class="treatment-key-group"> {| class="wikitable fna-keytable" |-id=key-0-1 |1 |Plants perennial, mat-forming; leaves in multiple rosettes. |[[Androsace chamaejasme|Androsace chamaejasme]] |-id=key-0-1 |1 |Plants annual or biennial, not mat-forming; leaves in single rosette |[[#key-0-2| > 2]] |-id=key-0-2 |2 |Involucral bracts relatively broad, ovate to lanceolate |[[#key-0-3| > 3]] |-id=key-0-2 |2 |Involucral bracts relatively narrow, lanceolate to linear-lanceolate |[[#key-0-4| > 4]] |-id=key-0-3 |3 |Calyx lobes subulate, stiffly erect, apex prominently acute |[[Androsace elongata|Androsace elongata]] |-id=key-0-3 |3 |Calyx lobes broadly lanceolate, erect, apex acute to obtuse |[[Androsace occidentalis|Androsace occidentalis]] |-id=key-0-4 |4 |Leaf blade bases abruptly narrowed to petiole; plants of wet areas. |[[Androsace filiformis|Androsace filiformis]] |-id=key-0-4 |4 |Leaf blade bases obscurely narrowed to petiole; plants of moist to dry areas. |[[Androsace septentrionalis|Androsace septentrionalis]] |} </div></div><!-- -->{{#Taxon: name=Androsace |author=Sylvia Kelso |authority=Linnaeus |rank=genus |parent rank=family |synonyms= |basionyms= |family=Primulaceae |distribution=North America;nw Mexico;Eurasia;mostly north-temperate areas |reference=None |publication title=Sp.
